<jats:title>Abstract</jats:title><jats:p><jats:bold>Carbon lights up</jats:bold>: A facile chemical method yields multicolor photoluminescent carbon dots derived from polymer/silica nanocomposites, which were prepared using surfactant‐modified silica spheres as carriers and resols (phenol/formaldehyde resins) as carbon precursor (see picture). The surface‐passivated carbon dots show good biocompatibility as potential bioimaging agents offering nanometer‐scale resolution.<jats:boxed-text content-type="graphic" position="anchor"><jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" mimetype="image/gif" position="anchor" specific-use="enlarged-web-image" xlink:href="graphic/mcontent.gif"><jats:alt-text>magnified image</jats:alt-text></jats:graphic></jats:boxed-text></jats:p>
